SELinux: remove needless sel_div function
I'm not really sure what the idea behind the sel_div function is, but it's
useless.  Since a and b are both unsigned, it's impossible for a % b < 0.
That means that part of the function never does anything.  Thus it's just a
normal /.  Just do that instead.  I don't even understand what that operation
was supposed to mean in the signed case however....
If it was signed:
sel_div(-2, 4) == ((-2 / 4) - ((-2 % 4) < 0))
		  ((0)      - ((-2)     < 0))
		  ((0)      - (1))
		  (-1)
What actually happens:
sel_div(-2, 4) == ((18446744073709551614 / 4) - ((18446744073709551614 % 4) < 0))
		  ((4611686018427387903)      - ((2 < 0))
		  (4611686018427387903        - 0)
		  ((unsigned int)4611686018427387903)
		  (4294967295)
Neither makes a whole ton of sense to me.  So I'm getting rid of the
function entirely.
